Applications with auxiliary functions
A standard actuator with corresponding functionality can be used if a ball valve
application requires a rotary actuator with auxiliary functions (e.g. auxiliary switch or
potentiometer). In this case, mounting kit ASK77.x is required in addition to the rotary
actuator.
Follow the mounting instructions when mounting.
